The transistor resistance is 27 ohms and the maximum current allowed is 140mA AC or DC with ambient temperature of up to 40°C. In order to get a "logic low" you have to limit the current to: logic low voltage required divided by 27, logic low voltage = 0.5V. I max = 0.5/27=0.0185A=18mA. If you intend to use other forms of communication, an optional Multi-slot Communication is available that will convert the RS232 serial commands into the following formats: w Ethernet, SNMP w J-Bus/RS422 w High
