Technical specifications
Input data:
20 input lines for BCD, binary or Gray code addressed and strobed
inputs can be used to give up to 8 digit display or special weighted
digital input (up to 8 inputs). For BCD inputs four of the 20 input
bits can be assigned for use as remote decimal point and display
hold if required.
Input types:
5V, 12V to 24V or 48V DC contact closure or open collector
(factory configured)
Input logic:
Selectable active high or low
Decimal point:
User selectable
Sample Rate:
4 samples per second
Microprocessor:
HC68HC11F CMOS
Ambient temperature:
LED -10 to 60
o
C, LCD -10 to 50

C
Humidity:
5 to 95% non condensing
Display:
LED Models: 4 digit 20mm,
5 digit 14.2mm + status LEDs + 4 way keypad
6 digit 14.2mm + 4 way keypad
8 digit 10mm + 4 way keypad
LED Bar Graph 20 segment bar + 5 digit 7.6mm + relay status LEDs
LCD Models: 4 digit 12.7mm, 6 digit 12.7mm
Power Supply:
AC 240V, 110V or 24V 50/60Hz
or DC isolated wide range 12 to 48V.
Special supply types 32VAC, 48VAC 50/60Hz or
DC isolated 50 to 110V also available.
Note: supply type is factory configured
Power Consumption:
AC supply 4 VA max, DC supply typically 80mA at 12VDC and
40mA at 24VDC for PM4 with no optional outputs, actual current
drawn depends on display type and options fitted

Optional outputs
Alarm relays:
1, 3 or 6 alarm relays (binary, Gray code, whole
number BCD (
bcd COdE
=
0
) and weighted digital input only).
Analog Retransmission: 12 bit isolated 4 to 20mA, 0 to 1V or 0 to 10V link selectable
(4-20mA output will drive into resistive loads of up to 800Ω)
(binary, Gray code, whole number BCD (
bcd COdE
=
0
) and weighted
digital input only)
Digital Retransmission: Isolated BCD/Binary
(binary, Gray code, whole number BCD (
bcd COdE
=
0
) and weighted
digital input only)
Serial Communications: Isolated RS232 or RS485 (ASCII or Modbus RTU)
(binary, Gray code, whole number BCD (
bcd COdE
=
0
) and weighted
digital input only)
