Pulse Output
The pulse output is a solid-state relay. Each pulse represents a user-defined volume. Because the circuit is
isolated, it can be used in conjunction with any other feature on the MC-III EXP. A two-conductor cable from
the MC-III EXP to the remote location is required (Figure 2.13). The maximum current rating of the pulse
output circuit is 60 mA at 30 VDC.
A Zener diode (Part No. 1.5KE56CA) must be installed for CE approval.
For information on configuring the pulse output with the keypad, see Configuring the Pulse Output, page
