1.0 Introduction
The SC-2124 is a microprocessor-based universal scanner for continuous monitoring of up
to 24 channels measuring temperature from thermocouples, pressure or any other analog
signal that can be represented by either 0-5V or 4-20mA . Each scanner channel may be
configured for the following input types:
•J, K, E, or T thermocouple inputs
•4-20 mA inputs (8 on-board resistors available via DIP switch)
•0-5 V Inputs
The SC-2124 provides ALARM and SHUTDOWN capabilities via two dedicated on-board 5
Amp relays (plus 2 additional general-purpose relays) and automatically TRIPs should any
user-programmable threshold be exceeded.
The SC-2124 utilizes all DB-Style Connectors on the back of the unit for a cleaner wiring
arrangement. All wiring to the unit is done via separate DIN-RAIL type terminal modules and
then DB-25/15 cables connect to the unit.
The SC-2124 front panel includes a large-character, 4-row by 20-column, backlit LCD display
and application keypad. The display has several Run Screens: a SCAN Screen that displays
each enabled scanner channel, one channel screen at a time; one or more Custom Screens
to display up to four user-specified scanner channels per screen; and a SNAPSHOT Screen
that displays each enabled channel’s analog input reading at the time of the last
SHUTDOWN plus indication of the “First-Out” channel causing the shutdown.
Utilizing an on-board RS-232 communications port with a convenient DB-9 connector, the
SC-2124 provides powerful communications capabilities. Quick and easy configuration is
done from a laptop computer using the Dynalco DYNALINK software. The unit can also
switch protocols and talk Modbus RTU for continuous remote monitoring.

2.0 Installation
Installation requires a cutout as shown in section 2.1 along with four mounting holes. Once
the unit is mounted, a nearby (less than 6 feet away) location is needed for performing the
wiring to separate terminals. One method is to purchase the optional DB-to-Screw-Terminal
modules which are DIN-RAIL mounted. Also, the supplied Cold Junction Compensation
(CJC) Sensor is necessary if any thermocouples are to be used. The Dynalco ETS-202 CJC
sensor should be mounted as close as possible to the location where the thermocouple wires
are terminated.

2.2 DIP Switch (Rear of Unit)
Channels 1 – 8 have a 100 Ohm resistor available across their inputs for use with 4-20mA
inputs ONLY. Only move the appropriate DIP switch to the “ON” side if that channel is to be
configured as a 4-20mA input.
If any inputs besides channels # 1 – 8 are to be configured for 4 – 20 mA, a 100 ohm resistor
will need to be installed across the corresponding input channel terminations on the terminal
block.
NOTE: Setting the DIP switch to “ON” for either a 0-5V or thermocouple input will result in
faulty operation of the SC-2124.

2.2 Wiring (Cont’d)
Connectors D and E are input terminals, each requiring p/n SC-CBLE25MM cable / terminal
block assembly.
Thermocouples can be connected to any input of either connector D or E.
For linear inputs (4 – 20 mA or 0 – 5 VDC) it is recommended to connect the wires to the
appropriate terminals for connector D. However, either connector D or E may be used. See
previous page for information on DIP switch settings for 4 – 20 mA inputs.
Any RTD inputs require the RTD module p/n SC-RTD, which includes the cable assembly. In
this case ,p/n SC-CBLE25MM will not be required. Note that (1) SC-RTD will handle up to 12
RTD inputs and can be connected to either connector D (Ch # 1 – 12) or connector E (Ch #
13 – 24).
Instructions for SC-RTD module configuration are in Appendix E.
Connector D (DB-25F)
This Connector provides the Analog Inputs for Channels 1 – 12.
