The ZB-2 module is a safety device protecting the output of any DC
power supply against overload. The output cut-off current is 1.7 A.
Additionally, the module is fitted with an NC type relay output to notify the
connected control panel of an overload occurrence.
ZB-2 is designed to work with devices that are not provided with current
limiter and overload indicator. Such devices are offered by SATEL and
include CA-64 EPS, CA-64 ADR, CA-64 PP, CA-64 OPS-R, CA-64 OPS-OC and CA-64
OPS-ROC expanders.
