Text for tenders: Wireless digital input


Wireless digital input

The wireless digital input is used for monitoring

messages from external systems. It may be operated

with the wireless I/O unit. In the event of

status changes, a message is sent to the central

wireless base system. The digital input is capable

of handling message signals of between

10 . 30 V DC.

The signal must be made available via the external

system. If the system to be monitored only has

a floating contact, the 24 V DC Rittal CMC-TC

power pack may be used.

The function Normally Open (NO) (normally open

alarm contact) or Normally Closed (NC) (normally

closed alarm contact) may be set directly on the

sensor at the push of a button. The sensor contains

a long-life 3.6 V lithium primary cell. The battery

may be replaced if necessary. It is mounted

using the mounting bracket enclosed with the

supply which may be secured e.g. to the enclosure

frame. The sensor is simply mounted on the

bracket. The battery and the radio connection

quality of the sensor are monitored.
