Pci's scaling and alarm modules
PCI offers a number of function modules for signal transmission, input alarming
and signal ramping. All of these modules include filtering and signal conditioning to
reduce susceptibility to transients and noisy operating conditions.
The Signal Transmitter provides dual DC signal outputs proportional to a DC input signal.
This product is very useful for scaling signal levels from one amplitude to another, as
well as for converting from voltage to current.
The Alarm Module monitors a DC input signal and provides two sets of SPDT, 3 amp alarm
relays, each having its' own adjustable setpoint and integral LED to indicate the alarm
status. The module can be supplied in either a HI/Hl, HI/LOW, or LOW/LOW alarm
configuration.
The Ramp Module produces a DC output signal over an adjustable time rate setting based on
the closure of a external contact. This module has integral LED's indicating that the ramp
module's output is at minimum, or has reached a maximum output state. The ramp module is
very useful for establishing the gradual opening or closing of a control damper.
Electronic to
Pneumatic Transducer
This device is utilized on electronic/pneumatic control systems for converting a DC input
signal into a proportional pneumatic output. The unique design of this transducer allows
for field setting of the pneumatic output range, as well as manual setting of the devices
output.
The E/P transducer is non-position sensitive nor is it susceptible to variations in
instrument air. This is due to the integral pressure transducer utilized to monitor and
control the devices final output value.
