Warning:

Use National Electric (NEC) or other country-specific standard wiring and safety practices when wiring and connecting this controller to a power source and to electrical sensors or peripheral devices. Failure to do so may result in damage to equipment and property, and/or injury or loss of life.

Note:

Maximum wire size termination and torque rating:

•0.0507 to 3.30 mm2 (30 to

12 AWG) single-wire termi- nation or two 1.31 mm2 (16 AWG)

•0.8 Nm (7.0 lb.-in.) torque

Note:

Adjacent terminals may be labeled differently, depending on the model number.

Switched DC

•30 mA dc maximum supply current

•short circuit limited to <50 mA

•22 to 32VÎ (dc) open circuit voltage

•Use dc- and dc+ to drive exter- nal solid-state relay.

•DIN-A-MITE compatible

•single-pole: up to 4 in parallel or 4 in series

•2-pole: up to 2 in parallel or 2 in series

•3-pole: up to 2 in series

Open Collector

•100 mA maximum output cur- rent sink

•30VÎ (dc) maximum supply voltage

•Any switched dc output can use the common terminal.

•Use an external power supply to control a dc load, with the load positive to the positive of the power supply, the load negative to the open collector and common to the power sup- ply negative.
