4.2.2 Pulse output
The pulse output provided by the RIM10 is a sinking type output only. A pull-up resistor is
required, and can be installed between pins 9 and 21 on the screw terminal block - See
Figure 21. The resistor value is dependent on the totalizer requirements. At 2 k, a half-watt
resistor is required. The pulse width is fixed to 50 ms. The load current is 100 mA max,
28 V peak.
4.2.1 dc power
Wire the dc power as shown in Figure 20 using 0.82 mm

(18 - 22 AWG) gauge
wire. The dc supply can be anywhere from 12 - 32 V, but 24 V is recommended.
On installation the RIM10 shall be provided with supply transient protection external to the
apparatus such that the voltage at the supply terminals of the RIM10 does not exceed
140% of the voltage rating of the equipment.
