Frequently Asked Questions (FAQ)

• What is a discrete relay I/O base? It is a combined module that provides both digital inputs and relay outputs for a PLC system.
• What types of loads can the relays switch? They are rated for resistive loads (lamps, heaters) and specific inductive loads (contactors, solenoids) as per the power ratings.
• What does "negative logic" input mean? The input is active (State 1) when the terminal is connected to 0V/negative, common with PNP sensors.
• How many devices can I connect? It has 16 discrete input points and corresponding relay outputs.
• What is the isolation rating? It provides 1500 V isolation between the relay contacts and the PLC logic for safety.
• Is it compatible with 3-wire sensors? Yes, it is compatible with both 2-wire and 3-wire PNP-type proximity sensors.
• How is it powered? It receives power from the TSX PLC rack's backplane (160mA positive, 131mA negative).
