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 -
SO - Output Transistor Rating: V
max
= 30 VDC, V
SAT
= 1 V
max
at 20 mA
SI - Input Diode Rating: V
F
= 1.25 V
TYP
; 1.5 Vmax
Note: The compliance voltage rating of the source must be greater than the
sum of the voltage drops around the loop.
12. OUTPUTS:
Solid-State - Current sinking NPN open collector transistors. I
SNK
= 100 mA
maximum @ V
CE
= 1 V. V
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.).
