Digital and field circuits are optically isolated. 

All modules feature isolation between digital and field circuits, resulting in increased

noise immunity and limited damage to your system due to an

electrical malfunction of the field wiring.

Self-lifting field-wire pressure plates cut installation time. 

Wiring terminals have self-lifting pressure plates to secure two #14 AWG

field wires.

Removable terminal blocks help ease the wiring task.

Removable terminal blocks allow you to replace the module without rewiring it

(not available on all modules).

Removable terminal blocks are color coded for quick identification.

A matching color band is also provided on the front of the module to

assist in matching the terminal block to the module.

Barrier-type terminal blocks provided on all modules. 

Each terminal block features a barrier on three sides of each terminal to help

prevent accidental shorting of field wiring.

Self-locking tabs secure the module in the chassis.

No tools are necessary to install or remove a module from the chassis. To install

a module, you slide it into the chassis until it latches in place.
