The TTL input is designed for a TTL level input (0 to 5 V). This input has a 30% hysteresis, that
means that the output will go to a high level when the input goes above about 3.4 V and will go
to a low level when the input voltage drops below about 1,6 V. The input frequency is limited to
about 10,000 Hz.
6.3 Auxiliary Inputs
An optional input exists for a remote "ON/OFF" 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. When programming the MT-02 this input must remain open.
6.4 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 : 8 A
Maximum Power : 250 VA
6.5 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.
