1.7 A to 3.5 A typ.

Wiring of the actuators Two 40-pin terminal blocks

For loads above 200 mA, a terminal diode is required for the inductive load

Recommended fuse

Groups of outputs must be protected by a 4 A/125 V fast-blow fuse (recommended: Littelfuse

235 004P 125 V 4 A). If the fuse is installed in a danger zone in accordance with the National

Electric Code (NEC), you must always use a suitable tool to remove it. Before removing or

replacing the fuse, you must determine whether or not you are dealing with a danger zone.

STEP 7 integration

64-channel I/O modules are integrated with the HSP 2019 V 1.0. The HSP forms part of

STEP 7 V 5.4 SP2 and can be installed from STEP 7 V 5.4 and higher.
