Input and output options for Multical 602 Heat Meter

Issue

What are the input and output options for the Multical 602 heat meter?

Product Line

Field Devices

Environment

standalone

LonWorks

M-Bus

Cause

The current datasheet, F-27718-2, for the Multical 602 & Ultraflow 54 Heat Meter is not clear about what input and output options are available and how they can be combined.

.

Resolution

The Multical 602 can be supplied with two internal modules - a top module with clock backup, pulse outputs or M-Bus and a base module with M-Bus or Lonworks.  Either or both modules may be omitted. There are several options for both the top and base modules.

Use the Order Specifications chart in section 8 of the datasheet to place the initial order.  Section 9 of the datasheet lists the individual parts, if you want to modify the meter later.

The current datasheet, F-27718-2, lists four top modules with pulse outputs.  Of these, only one is now available -  MAPULSEOPTOPC  c/w RTC + Hourly Data Logger + 2 Pulse O/Ps + Scheduler.

MAPULSEOPTOPA, MAPULSEOPTOPB and MAPULSEOPTOPD are all obsolete.

It is possible to combine any of the available top modules with any of the available base modules.  However there are restrictions on the power supply with some combinations.  See the following table:
