Product Usage Instructions
- Reed Switch: Reed Switch is a 2-wire device that triggers by the magnet inside the rotors as they spin. The pulse board comes equipped with a 1k8 current limiting resistor in series to maximize the life of the reed switch.
- Hall Effect Switch : Hall Effect switch is a 3-wire device that triggers by the south pole of the magnet inside the rotors as they spin. This switch is NPN type and equipped with a 4k7 pull-up resistor between signal and supply.

Cable Specifications for Standard Pulse Cap
Minimal cable specification recommended for wire
- 5 core, 24 AWG each
- drain wire AND shielding/ copper braiding
- Temperature rating : -20 – 80 °C
- Voltage rating : 300 V
- Maximum cable length should not exceed 60 metres.
- If cable is extended and/or longer than 10m, it is highly recommended to use 24V power supply for Hall Switch and reed switch.
DIN Pulse Cap
DIN Pulse Module Output Type (MXD-xx)
- DIN Pulse Module incorporates the M-LOCK (¼ turn) mounting system. It provides a locking facility for added security against unauthorised removal. A locking screw is supplied with DIN pulse cap to accomplish the job by fitting module to the flow meter using M-lock feature and replacing the existing screw with locking screw.
- During initial installation of the locking screw, the screw will need to pierce the bottom of the pulser.
- This will enable the screw to ‘lock’ into the plastic cam that is fixed to the flow meter.
The available options are
- DIN Module with 1 x Reed and 1 x Hall effect sensor (MXD-RH)
- DIN Module with Dual Hall Effect sensors (MXD-HH)
- DIN Module with Dual Reed Switches (MXD-RR)
Note
- DIN Pulse Cap Temperature (-25 °C -120 °C)
- IP 67
DIN Pulse Module
The DIN Pulse Modules accommodates the choice of either a field mountable connector facility, or a fixed (M12) connection cable.
- M12 DIN plug and socket complete with 5 core cable.
- Field attachable socket with 5 position screw terminals
