PR electronics 2231D Trip Amplifier, D

Features:

• The front-operated push buttons are used for programming the different standard functions.
• A password can prevent access to changing parameters.
• Alarm detector in connection with measurement of AC/DC current or voltage signals.
• The unit is used where accurate setpoint settings and different alarm functions are required.
• The unit can be used as a single or dual trip amplifier. Used in applications where programmable parameters such as hysteresis, setpoint, reset, active relay for increasing or decreasing signal, delay and input signal need to be set.
• 3-digit display showing the input signal in %.
• Two LED indicating relay status.
• 3 pushbuttons for programming.
• Standard DC current input signals in the range 0...20 mA.
• DC voltage signals in the range 0...250 VDC.
• AC current signals up to 1 A. True RMS measurement of AC voltage signals in the range 0...250 VAC.
• Mounting for a standard 11-pole socket which can be adapted for DIN rail or plate use with PR's 7023 adaptors and 7024 mounting keyings.
• Supply D - 24 VDC
