MC-II Pulse Output Circuit Assembly

(Part No. 100005163; Intrinsically Safe)

The pulse output circuit assembly (Figure B1) equips the MC-II Flow Analyzer to provide an optional pulse

output. It is mounted inside the unit between the totalizer board and the battery cavity.

Important—When this circuit assembly is installed according to Figures B2, B3 and B4 (pages 35 and

36), the MC-II with pulse output is rated by Canadian Standards Association as Intrinsically Safe for

Class I, Division 1, Groups A,B,C and D.

Pulse Input - Intrinsically Safe

The pulse input to this card is obtained from the “Pulse Out” of the totalizer card. It will appear in the form of

a square wave pulse.

Pulse Output - Intrinsically Safe

The pulse output from this card is provided in the form of a dry contact from a relay, transistor open-collector,

or an emitter/collector opto-isolated output. A 14-pin socket on the card is provided to install either the relay

or component plug “module”, whichever is specified.

Electrical Specifications - Intrinsically Safe

Current Required

10 mA

Relay Contact Rating

200 mA, 6 VDC

Open Collector Module

200 mA, 6 VDC

Opto-Isolated Module

100 mA, 6 VDC

Pulse Output Duration

60 msec (approx)
