Using 3-phase input reduces the ripple on the internal DC bus compared to 1-phase (15.0A nominal), which extends the service life of the internal capacitors and improves heat management.\n    \u003c\/p\u003e\n\n    \u003cp style=\"font-weight: bold; margin-bottom: 5px; color: #333; margin-top: 20px;\"\u003eQ2: Can I run this drive without the 24V DC back-up power supply?\u003c\/p\u003e\n    \u003cp style=\"margin-top: 0; padding-left: 15px; border-left: 3px solid #ccc; color: #555;\"\u003e\n      A2: Yes, the drive will function on AC power alone. However, without the 24V DC backup, the drive will lose its EtherNet\/IP network identity immediately upon AC power loss.

However, because this module lacks internal electronic short-circuit protection, an accidental short on a 24V field wire directly connected to an output pin will permanently damage the internal output transistor. To prevent hardware damage during commissioning or wire degradation, we strongly recommend installing external SAN-O MQ4-800 mA fast-acting fuses on individual output channels or utilizing a fused terminal base assembly. Furthermore, when switching inductive coils, fitting suppression diodes across field load terminals absorbs back-EMF spikes and prevents premature transistor fatigue.\u003c\/p\u003e\n\u003ch3\u003e\u003cb\u003eFrequently Asked Questions (FAQ)\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eQ: What causes an output channel on this module to fail permanently in a closed (always ON) position?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eA:\u003c\/b\u003e Overcurrent shorts or high inductive voltage spikes exceeding the transistor's thermal limits typically break down the solid-state output junction, causing it to short internally and stay ON; installing SAN-O MQ4-800 mA fuses prevents this failure mode.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eQ: Can field loads requiring 12V DC power be driven reliably using this output card?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eA:\u003c\/b\u003e Yes; the module supports an ON-state voltage range from 10V DC up to 31.2V DC, allowing it to switch 12V DC control loads provided the auxiliary power supply matches the load voltage requirement.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eQ: How many of these discrete output modules can be installed under a single Flex I\/O adapter node?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eA:\u003c\/b\u003e Up to eight modules can be mounted sequentially on a single Flex I\/O backplane cluster, provided the total 5V DC Flexbus current draw of all cards does not exceed the adapter's power supply rating.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eQ: Why does a 24V LED indicator connected to an inactive channel stay faintly illuminated?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eA:\u003c\/b\u003e The 0.5 mA off-state leakage current inherent to solid-state output transistors can pass enough residual energy to faintly light high-efficiency LED indicators; placing a parallel resistor across the load bleeds off this voltage.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eQ: Selection Guide: How do I choose between specifying the 1794-OB16 sourcing card and the 1794-OV16 sinking output card?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eA:\u003c\/b\u003e Select the \u003cspan style=\"color: #0056b3;\"\u003e\u003cb\u003e1794-OB16\u003c\/b\u003e\u003c\/span\u003e when field actuators require current-sourcing logic (+24V DC switched to the load).

field loads must have their opposite lead connected to the DC common rail. Because all 16 channels share a single internal DC power rail without channel-to-channel isolation, an accidental short on one output line can blow the main branch fuse or trip the power supply, affecting adjacent channels. When wiring inductive loads such as 48V solenoids or large relay coils, always install external flyback diodes across field load terminals.

The 2.25 mA maximum leakage current can keep low-power loads—such as high-impedance digital inputs or high-efficiency LED indicators—partially energized when the channel is OFF. Conversely, field loads drawing under 5 mA will fail to latch the triac ON.

However, pay close attention to external supply stability; always supply a clean, unswitched +24V DC line to the module's power terminals. Voltage dips on the 24V DC auxiliary supply can cause minor variations in coil energization timing, which may momentarily force a single contact to bear full inrush load during group switching operations. Additionally, when driving highly inductive loads, installing external MOV surge suppressors directly across field coils will preserve internal relay contacts beyond the 100,000-cycle minimum design threshold.\u003c\/p\u003e\n\u003ch3\u003e\u003cb\u003eFrequently Asked Questions (FAQ)\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eQ: What field symptom indicates that the internal RC snubber circuit is interacting with a low-power AC load?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eA:\u003c\/b\u003e Low-current AC loads (such as high-impedance LED indicators or small relays) may stay partially energized or flicker when the contact opens due to the 1.0 mA max off-state leakage current passing through the snubber circuit; placing a parallel bleeder resistor across the load resolves this issue.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eQ: Can a 24V DC load and a 230V AC load be wired simultaneously on adjacent channels of the same module?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eA:\u003c\/b\u003e Yes.
