8.2.1 mA output
The mA output is available on the back panel of the
PMA100 (see fig.8) at the 15-pole Sub-D socket X3. The
following figure shows the configuration of the terminal.
For multichannel version the outputs are arranged as
follows:
1
channel 1,
2 channel 2,
3 channel 3,
4 channel 4.
The menu-driven handling of the mA outputs is described in
chapter 12.
8.2.2 In- and output contacts
Fig. 9 shows the configuration of the terminal X4. The
following connections are available at the 25-pole Sub-D
plug:
• four binary inputs, In1 to In4, with 12V - 24V, max. 20mA,
• four binary output contacts, Out1 to Out4, with 48V,
max. 500mA,
• one alarm contact, Alarm MC and Alarm NO, with 48V,
max. 500mA,
• one status contact output, Status MC and Status NO,
with 48V, max. 500mA. and
• one supply power contact, Out +24V and Out 0V, with
24V, max. 100mA.
The menu-driven handling of the in- and outputs is
described in chapter 12.
8.2.3 Connector for solenoid valves
Fig. 10 shows the 25-pole Sub-D socket X5 with the supply
power to control three external solenoid valves. At the moment
three conections are available:
• pin 2 connection for the zero gas solenoid valve, 24V,
max. 400mA,
• pin 3 connection for the span gas solenoid valve, 24V,
max. 400mA, and
• pin 5 connection for the sample gas solenoid valve, 24V,
max. 400mA.
The menu-driven handling of the in- and outputs is
described in chapter 12.
