■ Description
■ Special Features
This signal conditioner is a dual or quad-channel
analog input module with one discrete/relay output per input channel and a Modbus interface. It
filters and linearizes RTD or resistance inputs
while providing isolation between input, output,
power, and network circuits. Lead wire compensation and upscale/downscale sensor break
detection are standard. Low voltage AC and DC
power sources are supported with nonpolarized,
diode-coupled terminals.
■
Standard Modbus RTU protocol with high-speed
RS-485 communication (up to 115K bps)
■
16-bit sigma-delta A/D yields 0.1°C resolution
and 0.25°C accuracy (Pt, Ni RTDs)
■
RTD linearization and sensor break detection
ensure reliable measurements
■
Discrete relay outputs enable local temperature
limit alarms or host-controlled on/off switching
■
Heavy-duty 1A solid-state relays provide
dependable on/off control of industrial devices
■
Self-calibration lowers maintenance costs by
reducing periodic manual calibration checks
■
Watchdog timers provide a configurable
failsafe output state for use when host
I/O communication is lost
■
Four-way isolation eliminates potential ground
loops between power, input, output and
network circuitry
■
Self-diagnostics monitor microcontroller activity
to detect operational failures (lock-up) and
execute a reset to restore communication
The programmable inputs accommodate four
RTD types plus wide-range resistance signals.
Flexible discrete outputs operate as alarms or
on/off controllers. As limit alarms, each discrete
output can be configured with high and/or low
setpoints exclusively tied to an analog input
channel. Alarm trips function without host communication enabling low-cost stand-alone alarms
as well as local backup for the primary control
system. Otherwise, on/off control is based on
commands issued by the host system.
Combining flexible transmitter functions, mixed
signal I/O, alarm support, and a network interface in a single package, makes this instrument
extremely powerful. Multi-channel design adds
cost-efficiency and allows high-density mounting.
Plus, safe, rugged construction makes these
modules reliable for use in both control room
and distributed field I/O applications. Custom
module configurations are also possible (consult
factory for details).
