Operation
Figure 5.1 MS-1DIN2 & MS-2DIN2 Control Module
•T11 Address Enable Open: When the terminals are
shorted, the Module Number cannot be changed from a
master on the data highway. (MS-1 & MS-2 terminals 24
and 25). 1 & 2-point models only.
• T12 Heater Power Input: 280Vac max input voltage. (MS-
1 & MS-2 terminals 28, 29, 32 and 33, MS-5A & MS-10A
terminals 20-39). Mechanical models only.
• T13 Heater Power Output: 280Vac/30A max continuous
(MS-1A & MS-2A terminals 30, 31, 34 and 35, MS-5A &
MS-10A terminals 40-59). Mechanical models only.
• T14 +15Vdc Power Output: 15Vdc/0.2A. (MS-5A & MS-
10A Terminals 15 & 16). 5 & 10-point models only.
• T15 TC Input: Thermocouple input. There are 10 TC in-
puts, one per heater (Terminals 60 & 61 for TC1, 64 & 65
for TC2, ..., 96 & 97 for TC10). Connect TC’s positive wire
to terminal marked as (+), and negative wire to terminal
marked as (-). Model MS-10ADIN2T only.
• T16 Xmitter Input: RTD Transmitter input. There are 10
Xmitter inputs, one per heater (Terminals 60 & 61 for
Xmitter1, 64 & 65 for Xmitter2, ..., 96 & 97 for Xmitter10).
To connect with an RTD Transmitter, use 18 AWG wires
to connect the terminal marked as + to the I(+) terminal on
RTD Transmitter, and the terminal marked as - to the I(-)
terminal on RTD Transmitter. The actual RTD sensor is to
be locally wired to the RTD Transmitter and the transmit-
ter can be located up to 7km away from the control mod-
ule. Model MS-10ADIN2X only.
• T17 +15Vdc Power Output: Model MS-10ADIN2X only.
5.1.4.Communications Ports:
•C1 ML100 Interface: Standard connection to a Dedi-
cated Interface Module via a ribbon cable.Maximum ca-
ble length is 4 feet.
•C2 Serial Port 1: Standard connection to an RS-485 data
highway via a 2-conductor, shielded, twisted pair cable.
Maximum Cable length with 30 Control Modules without
repeater is 4,000 feet. (MS-1 & MS-2 terminals 18+, 19-, 20
SHD, MS-5A & MS-10A terminals 8+, 9-, 10 SHD)
•C3 Serial Port 2: Standard connection to an RS-485 data
highway via a 2-conductor, shielded, twisted pair cable.
Maximum Cable length with 30 Control Modules without
repeater is 4,000 feet. (MS-1 & MS-2 terminals 21+, 22-, 23
SHD, MS-5A & MS-10A terminals 17+, 18-, 19 SHD)
•C4 Serial Port 3: Standard connection to an RS-485 data
highway via a 2-conductor, shielded, twisted pair cable.
Maximum Cable length with 30 Control Modules without
repeater is 4,000 feet. (MS-5A & MS-10A terminals 20+,
21-, 22 SHD). 5 & 10-point models only.
This port is specifically designed for the communica-
tion between the control module and the RTD Sampler. If
communication is conducted via wireless RF Modem, the
RS485 cable should be wired to the RF Modem mounted
on control module nearby. If communication is conducted
via RS485 cable, the RS485 cable should be connected to
the RTD Sampler’s communicaiton port directly.
