Automation Components, Inc. A/CP-RS-A34-C6

The ACI room transmitter series features a two-wire 4~20mA loop-powered output, with an optional three-wire voltage output signal. All transmitters include zero and span adjustment for field calibration and are calibrated using NIST-certified calibration equipment. ACI recommends using 18~22 AWG shielded cable in all temperature transmitter installations to reduce the possibility of noise being introduced on the signal lines. Room transmitters are designed for installation on a standard single-gang junction box or wall opening. For optimum accuracy, ACI recommends the A/TTM series matched transmitters with 3-point or 5-point NIST calibration certificates, as they include a second calibration step in which the RTD and transmitter are calibrated together as a system. The A/TTM series matched transmitters include a foam gasket to reduce the effects of transmitter self-heating and warm air convection from within the wall. An optional LCD display is available with setpoint, override, and loop-powered features.
