Description
The M4500, M4600 and M4700 Indicator Panels are intended
for status indication of any process providing on/off outputs.
The panels contain 6, 8 or 20 channels, respectively.
An input through a dry contact will light the corresponding LED.
These panels are an ideal solution for local or remote indication
of the output signals from, for example, a PLC or from alarm
monitors such as the M1000. The 20 channel M4700 is available
in a version with built-in alarm and siren relays.
M4780 is a versatile 20 channel indicator panel which can
be used for monitoring of dry contacts and signal states
transmitted through a common 2-wire RS485 communication
bus using the MODBUS-RTU protocol. This unit is a
combination of a traditional indicator panel with dry contact
inputs and a MODBUS indicator panel. M4780 can also work
as an alarm monitor using two internal relays for group alarms
and control of an external siren. An internal siren for local use
is built-in. Via the MODBUS-RTU a PLC can read the state of
the LEDs and the inputs on the M4780. This feature makes
the M4780 a cost effective 20 channel digital input device with
indications in PLC systems.
