Engineering Advantages

Sixteen sinking channels fit into a single slot, maximizing rack density. Each channel carries a dedicated LED indicator for at-a-glance field signal verification and troubleshooting. The 1 mA off-state current prevents false triggering from line leakage. Faster 15 ms response on DC signals suits time-critical interlocks. At roughly 0.35 kg, the module adds minimal weight to the chassis. It mounts directly to any 1746 local or expansion chassis bus connector.

Technical FAQs

Q1: How many channels and what voltage does it accept?
A1: 16 sinking channels at 24VAC/VDC nominal, operating over 10–30V.

Q2: What is the signal delay for AC versus DC?
A2: 15 ms for DC signals and 25 ms for AC signals on both transitions.

Q3: How much backplane current does it draw?
A3: 0.085 A at 5V DC, with 6 W total power consumption.
