MINI MCR-SL-UI-REL(-SP)
Data Sheet 11/2004
Method of Operation
The configurable 3-way threshold value switch
MINI MCR-SL-UI-REL(-SP) is used to control and
monitor analog standard signals.
On the input side, the analog standards signals
0...20 mA or 0…10 V per DIP switch can be set. On
the output side, a relais with PDT contact is available.
The switching thresholds are set via a potentiometer.
The DIP switches that can be accessed at the side of
the housing allow for configuration of the following
parameters:
– Input signal area,
– Switching hysteresis,
– Relay dropout delay,
– Switch-over between operating current / closed
circuit current.
The voltage supply (19.2...30 V DC) can either be provided
via connecting terminal blocks "7"/"8" of the
modules, or together, via the DIN rail bus connector
(see Figure 5 on page 5). Please also observe "Power
Supply" on page 6.
