How to Select an Interface Relay for PLC Outputs
A step-by-step guide to matching PLC output type, coil voltage and current, contact rating, and socket style when selecting an interface relay.
The Schneider Electric NTSPFB1002HK is a Modicon Edge I/O NTS power distribution module kit that feeds both the I/O bus (3.5 A) and the field supply (10.5 A) from a 24 V DC input, pre-assembled on its NTSXBA0103H base for severe-environment use. It protects against overvoltage, overload, short circuit and reverse polarity on both rails, running across an extended -40...70 degC range with conformal-coated electronics. It mounts on a DIN rail at the head of an NTS cluster.
The NTSPFB1002HK feeds both the bus (3.5 A) and field (10.5 A) rails from a single 24 V DC input, the simplest choice for a cluster where all downstream I/O modules share one field voltage. When the field devices need a separately fused or switched supply from the bus electronics, the field-only NTSPFD1002HK is the correct module instead, paired with a separate bus supply upstream. The hardened build's conformal coating and -40...70 degC range matter in panels exposed to vibration or condensation.
