The compact design of the 4621273E safety evaluation unit allows it to be used even in applications with limited space.

A potential-free safety output in SIL3/PLe up to 4A and a control output with change-over contacts up to 3A are available. A maximum of 4 sensors with normally open/ normally closed contacts can be connected. Input expansion units (interfaces) can’t be used. Due to the 24V AC and DC supply voltage, the unit can be used for a wide range of applications.

The 4621273E can be used as a pin-compatible replacement for

462121E1
462121E1U (Note: different operating time)
462121E101
462121E1U1 (Note: different operating time)
462121E104
462124E1 (Note: different operating voltage AC 230 V)
462124E1U (Note: different operating voltage AC 230 V and different operating time)
462121H1
462121H1U (Note: different operating time)
462121H5
462121H5U (Note: different operating time)
