5. Check the Baud Select jumper on the
S6104 for the communication speed of the
Access Port (9600 or 38.4K). If the jumper
needs to be changed, turn the module’s
power off first. The baud rate change
registers when the module is turned on.
6. In SuperVision, define the connection type
using Table 3.
Inputs
The S6104 provides 10 universal inputs. If you
are wiring the S6104 module to a LogiStat or
LogiStat Plus sensor, inputs 9 and 10 can be
disabled, allowing temperature and setpoint
adjust inputs to be read through the LogiStat
Port instead (see “LogiStat Wiring” on
page 10). Refer to Table 4 for information
about wire length, gauge, and shielding.
NOTE On an ARC156 network segment,
inputs can be read through a LogiStat,
LogiStat Plus, or LogiStat Pro. However, on a
legacy CMnet, inputs can only be read on a
LogiStat or LogiStat Plus.
• Thermistor: Precon type 2 (10 kohm at
77°F). Input voltages should range
between 0.489V and 3.825V for
thermistors.
• 0 to 5VDC: The output impedance must
not exceed 10 kohms. The input
impedance of the S6104 is
approximately 1Mohm.
• 0 to 20mA: The input resistance on the
A input is 250 Ohms. The B terminal
supplies a voltage source to power the
4-20mA transducer. The B terminal is
capable of supplying 18 to 24VDC, but
the total current of all B terminals must
not exceed 200mA. If the voltage
measured from the B terminal to Gnd is
less than 18VDC, you need to use an
additional external power supply.
• Dry Contact: A 5VDC wetting voltage is
used to detect contact position. This
results in a 0.5mA maximum sense
current when contacts are closed.
