B. Input IN 2 LVTTL
The input signals IN 2 and IN 2 Rtn provide an interface to a TTL or LVTTL input signal
(Figure 68). The signal level (voltage difference between the inputs IN 2 and IN 2 Rtn)
must be
LVTTL (3.3 volts) or TTL (5.0 volts). The total maximum input current
must not
exceed 2.0 mA.
Figure 68: IN 2 Electrical Connection.
C. Output OUT 1 LVTTL
Output OUT 1 is a 5v TTL (5.0 Volts) compatible signal and the maximum output current
must not
exceed 8 mA (Figure 69).
Figure 69: OUT 1 LVTTL Electrical Connection.
D. Output OUT 2 – Solid state relay, optically isolated
Output OUT2 is an optically isolated switch. There is no pull-up voltage on either contact.
External pull-up voltage of up to 25 volts is required for operation. Output is not polarity
sensitive. AC or DC loads are possible. The voltage across OUT2 Contact 1 and OUT2
Contact 2
must not
exceed 25 volts and the current through the switch
must not
exceed
50 mA. On resistance is less than 5 Ohms.
