Terminal Blocks
This table includes descriptions for the following terminal blocks.
Block Number Block Description
140CFA04000 The A block is a straight through point to point connection on the
terminal block. Wiring of this block is identical to wiring the Quantum
I/O connector (140XTS00200).
140CFB03200 The B block is used for individually fused 2-wire digital inputs. This
terminal block is designed to prevent a single point failure from
affecting the remaining inputs. It is not recommended for sourced 1-
wire inputs (powered from the field).
140CFC03200 The C block provides connection for 32 group fused input or output
points. The block may be used for 1- or 2-wire inputs or outputs, and
features a fuse per group, four groups total. Users select input or
output mode via four switches located on the module. (The default is
input mode.)
140CFD03200 The D block is used for sensors requiring either 2- or 3-wire electrical
interface. A fuse per group is supplied to accommodate the I/O
module (4) groups.
140CFE03200 The E block provides connection for 32 individually fused 24 Vdc
outputs. 1- and 2-wire interfacing may be selected. Field power must
be supplied to the four groups.
140CFG01600 The G block is a high power output block used on both AC and DC
circuits requiring up to 2 A. Individual fusing is provided and may be
used in both 1- and 2-wire installations. It is also used for isolated AC
modules.
140CFH00800 The H block is used for analog inputs, with individual fusing provided
per channel. This interface provides plus, minus, shield, and power
supply interface for both field and loop power configurations.
140CFI00800 The I block is used for analog inputs. This interface provides plus,
minus, shield, and power supply interface for both field and loop
power configurations.
140CFJ00400 The J block is used for analog outputs, with individual fusing provided
per channel. This interface provides plus, minus, shield, and power
supply interface for both field and loop power configurations.
140CFK00400 The K block is used for analog outputs. This interface provides plus,
minus, shield, and power supply interface for both field and loop
power configurations.
