7.3 Auxiliary Inputs
An optional input exists for a remote "RESET P" to start batching processes. This input is designed
to take a normally open electrical contact between terminals Nº1 and Nº2 of the connector. For this input to
be effective it must be closed during about 200 milliseconds in order to start the batching process. In the
event of using this input to start batching processes, the relay will be activated on closing the contact,
without having the screen displaying "Press ENTER".
7.4 Relay Outputs
The output to control the batching processes is by means of an electro-mechanical relay with the
following characteristics:
Maximum Voltage : 250 V
Maximum Current : 1 A
Maximum Power : 30 VA
7.5 4 - 20 mA Output (Optional)
The MC-01 has a version with an analog output for 4-20 mA, 0-20 mA, 2-10 V, 0-10 V, 1-5 V o 0-5
V. The standard output is for 4-20 mA. The other options are available but must be specified with the order.
It is possible to change the type of output configuration, but this must be done by an authorized technical
service.
The analog outputs are active outputs, this means that the electrical current is supplied by the MC-
01. The characteristics of the loads that can be applied to this output are the following:
0-20 mA y 4-20 mA
= Maximum load resistance - 350 ohms
0-5 V y 1-5 V
= Minimum load resistance - 100 KΩ
0-10 V y 2-10 V = Minimum load resistance - 200 KΩ
7.6 Working Conditions
Ambient Temperature : 0 to 60 ºC
The housing is IP 30 at the rear and IP 50 at the front when mounted in a panel. An IP 65 protection
is available for the front of the housing.
