3 M-Controller Specifications
NOTICE: Installing or using this equipment in a manner not specified by
the manufacturer could cause electric shock, bodily injury, or
risk of fire.
Specification:
Power Supply Voltage: 24VDC nominal, range 18 to 30VDC
24VAC nominal, range 15 to 24VAC 50/60HZ
Note: M-Controller II has full-wave rectifier and half-wave
rectifier circuit on board for flexibility. You will damage devices
if you mix half wave and full wave rectifiers on the same AC
source. Use extreme caution when sharing a common AC
source. Sharing a common DC source is less problematic.
Current: M-Controller: max. 1.0 A (fuse protected)
Total actual power is dependent on the system design. The
power may be supplied to sensors and modules, or each may
have separate power supplies. Each type of sensor varies in its
power requirements.
Note: No external overcurrent protection is required. Over-
current protection is provided by means of fuses F1 and F2. See
fuse specification below.
Fuse F1, F2 on Main Board: Polyswitch 750mA
Polyswitch device resets after the fault is cleared and power to
the circuit is removed.
Power Switch Slide switch on circuit card (SW1). This switch disconnects power
to the main circuit cards and LCD display.
NOTICE: A switch or circuit breaker must be provided in the
installation, which can remove power from the M-Controller in
case of emergency or any other related requirement.
Since the M-Controller enclosure can be locked to prevent
unwanted tampering, the internal power switch is not
guaranteed to be accessible.
