11. SERIAL COMMUNICATIONS:
Type - Bi-directional 20 mA current loop, 20 mA source provided. (Powers up
to 7 units in a loop with internal current source.)
Baud Rate - Programmable 300 to 2400.
Maximum Address - 16 units.
(Actual number in a single loop is limited by
serial hardware specifications.)
Data Format - 10 bit frame, Odd parity
(one start bit, 7 data bits, one odd
parity bit, and one stop bit.)
Serial Hardware Specifications -

OH
= 30 VDC max. (Internal Zener diode protection).
Relays - Mounted on a field replaceable PC board. Form C contacts rated at 5
amps @ 120/240 VAC or 28 VDC (resistive load), 1/8 H.P. @ 120 VAC
(inductive load). The operate time is 5 msec nominal and the release time is 3
msec nominal.
Relay Life Expectancy - 100,000 cycles at Max. Rating.
(As load level
decreases, life expectancy increases.)
Programmable Timed Outputs - The timed outputs can be set from 0.01 to
599.99 seconds, ±(0.01% + 10 msec.).
