Since each input/output (I/O) module is independent from the other, the M3x5 can be
supplied with two different modules (for example 2 energy contacts and 2 alarm contacts) or
with two similar modules (for example 4 analogue outputs or 4 tariff inputs).
The wiring diagrams for the I/O modules fitted are shown on labels attached to the product
I/O module 1 uses terminals 15/16/17 and module 2 uses 18/19/20.
8.7.1 Energy Pulse Outputs
The 2 energy pulsed outputs can be used for external monitoring of energy consumption.
The energy measurement value output via the pulsed outputs corresponds to the basic
energy measurement on the
M3x5 display. The pulsed outputs' energy measurement can be
adapted to the customer’s needs using the QDSP2 configuration software via the
communications link.
FIGURE 8-14: DUAL ENERGY CONTACTS
The pulse output module has three terminals, the energy contacts share a common
connection but each contact can be individually set.
8.7.2 Tariff Inputs
The 2 tariff inputs can be used for signalling different tariff periods. The tariff period would be
used in conjunction with the Cost Management feature to determine the financial value of
energy being monitored. This corresponds to the energy costs on the
M3x5 display. The
tariff structure can be adapted to the customer’s needs using the QDSP2 configuration
software via the communications link.
The tariff input module has three terminals (see Figure 8-15) and shares a common
connection but each input can be individually set.
