Description
The KR 3A safety relay JOLA is designed for limit level signalling (sensor 1) or for two-point monitoring (sensor 2). They shall be installed in a control cabinet or other suitable protective enclosure. The switches are suitable for use in clean environments.
DIN rail mounted protective relays with connection terminals on top of the housing and 2 built-in LEDs to indicate the corresponding switching status.
These units are designed to be mounted or installed in a switch box in a suitable protective enclosure and can therefore only be installed in these locations. Suitable for use in clean environments only
