The WMS series connector permits eight channels per I/O group, up to 32 I/O per module, and a maximum of 480 discrete I/O on a single twisted pair. Wiring inside the control panel is connected to the terminals of firm's multi-pole connector block adaptor, available in screw clamp and crimp contact versions. Modules are rated for 24 vdc and 8 mA nominal output with outputs of -0.5V and 0.5A per channel.
