The EB3C-R03AN is a three-channel discrete input relay barrier with isolated common signal and relay output. The input contacts can be used in any explosive gas and Zone-0/Class I, Div. 1 location. Dry-contact switches with 0.5Ω maximum contact resistance can be connected to the device. It offers universal ac power voltage (100 to 240 Vac) and requires no grounding. Idec’s original spring-up terminals minimize wiring time and installation is via 35-mm-wide DIN rail mounting or direct panel mounting.
