• AC/DC trip amplifier
• 2 adjustable alarm limits
• Galvanically isolated 3.75 kVAC
• Front-programmable
• 3-digit LED display
• 24 VDC or universal supply
Applications:
Alarm detector in connection with measurement of AC/DC current or voltage signals. The unit is used where accurate setpoint setting and different alarm functions are required. The unit can be used as a single or dual trip amplifier. Alarm detector can be installed in PELV and SELV circuits.
Technical characteristics:
General:
The unit is microprocessor-based, which allows a very accurate setting of process parameters. Each unit is supplied with basic calibration data, which eliminates the tolerances in the component data. This means that the input can be programmed to the requested signal range without re-adjustment. Measurement ranges less than the min. measurement range of 0.5 V down to 10 mV may be entered, though affecting the resolution and the response time. Please note that the electric specifications of the module are only kept as long as the stated min. measurement ranges and max. zero off-sets are not exceeded.
Input:
Standard DC current signals in the range 0...20 mA. The current signal is detected by a 50 # shunt, which is manually connected through an internal jumper.DC voltage signals in the range 0...250 VDC. By measurement of AC current signals up to 1 A from a current transformer or current clamp a 1 # / 2 W input shunt is used. True RMS-measurement of AC voltage signals in the range 0...250 VAC, with a crest factor < 5. |
