R-C-A are from Catalytic bead sensors. 4-20mA may be applied to
any channel’s C & A terminals by addition of 100 ohm resistor
(R1-R8) and setting LEL/4-20mA jumper to 4-20mA.

OPTIONAL RTD / 4-20mA ANALOG INPUT BOARD # 10-0170
An optional 12 bit
RTD Sensor Input
board, shown in Figure 3.6, allows these popular
temperature sensors to be connected directly to the C1 without additional signal
conditioning or transmitters. A 3 position range jumper allows setting the gain of the
input bridge amplifier for the three popular ranges of 0-100°C, 0-200°C or 0-400°C.
Other ranges are available by special order.
Inputs may also be configured to accept 4-20mA signals, allowing mixing RTD sensors
and current loops into the same board. Two jumpers per channel determine either a RTD
or 4-20mA input. These dual position jumpers, JP1 – JP16, must both be placed into the
UP position for RTD inputs or both in the DOWN position for 4-20mA inputs (see Figure
3.6).
Channels receiving input data from this board should have the
Data From:
menu set for
Sensor,
as described in section 2.2.4. This activates
Cal Mode
menus, described in
section 2.2.9, needed to perform
zero
and
span
calibrations of RTD sensor readings.
