LCD Indicators


Product Description:

The ACI/LCD is a low power, high accuracy, 3.5 digit display module. The display can be calibrated to show any range between (-) 2004 and 2004 and has factory set descriptors which include C, F, mA, and a decimal point.

Another notable feature of the ACI/LCD is its wide operating temperature range of 0 to 70°C (32 to 158°F).

The ACI/LCD is available as a wall mount room unit which can incorporate any ACI sensor and is available with setpoint and override options. A separate 2 pole terminal block will be included for tenant override.

The setpoint options include a linear 400 Ohm, 1K, 2K, 5K, 10K, 20K, or 100K potentiometer. An optional series resistor allows for any offset of the setpoint potentiometer. The setpoint labels available are Cool|Warm, 55 to 85, and 10 to 30°C.

The ACI/LCD may be loop powered from a 4 to 20 mA signal, or powered by either 24 VAC or 8 to 35 VDC. When ordering, please specify your desired input.

The heart of the ACI/LCD temperature reference is a precision semiconductive temperature sensor calibrated to +/- 0.2°F accuracy. The +/- 0.2°F high accuracy unit is calibrated to an NIST Traceable thermometer.
