Allen-Bradley 194E-E40-PII Auxiliary Contact Block

Allen-Bradley 194E-E40-PII Auxiliary Contact Block is an accessory for the 194E family of load switches that provides an additional set of contacts for signaling and interlocking without carrying the main load current. It mounts to compatible 194E base units to extend the switch’s control and monitoring capability by adding auxiliary contacts. In the 194E line, auxiliary blocks are offered in various configurations, including 1 normally open and 1 normally closed (1NO 1NC) and 2NO 2NC, with suffixes such as P11, PL11, P22, or PD10 indicating the contact arrangement. Typical applications include status indication, interlocking, and control logic for motor starters, breakers, and other industrial equipment where a remote or local indication of the switch state is required.
