panel-mount LED indicator

Product catalog summary

Overview: The EM20-FPSI 1010 is a dual-color voltage level indicator designed for easy panel mounting. It compares input voltage against a defined window and uses a red-green-red LED display to indicate whether the voltage is below, within, or above this window. It operates within a 0 to 30V measurement range and requires a 7 to 24V DC supply.

Features:

Bright red and green LED indication.
Measurement range of 0 to 30V.
Operates on a 7 to 24V DC supply.
Two user-programmable thresholds with built-in hysteresis to prevent chattering.
One alarm output for external alarm or process control.
Low power mode with flashing LED indication.
Metal bezel with IP 67 / NEMA 4X protection.
Screw terminal connections for easy setup.

Applications: Suitable for go-no-go indication, level monitoring, alarm indication, and control applications.

Safety and Compliance: To comply with the Low Voltage Directive (LVD 93/68/EEC), input voltages must not exceed 60V DC. The device must conform to BS EN 61010 safety standards.

Electrical Specifications:

Supply voltage: 7.0 to 24.0 V DC.
Supply current: 15 mA (non-flashing).
Internal resolution: 30 mV DC.
Accuracy: 2% overall error.
Temperature stability: 100 ppm/°C.
Operating temperature range: -30 to 50°C.
Input impedance: 1 kOhm.
Output high voltage: 4.175 to 5.125 V DC.
Output low voltage: 0 to 0.6 V DC.

Configuration: The module is factory-configured with color switching thresholds at 11.0V and 22.0V. Users can adjust these settings by applying desired voltages and using a jumper link to store the new thresholds.

Installation and Connection: The module requires a 20.5mm diameter cut-out for mounting and is secured with a nut. It features screw terminal connections for power and input voltage. The alarm output can drive external devices like relays or triacs, with a maximum source current of 1mA.

Additional Notes: The module's rear is potted to prevent water ingress, and it includes a compressible silicone seal for front protection. The flashing mode timing is specified with t1=0.1s and t2=3.6s.
