When the control bit is set to a “0”, the discrete output is driven to ground.
When the control bit is set to a “1”, the discrete output floats. The CEI-
220 supports four outputs. The CEI-420/420A support 8 outputs. The
CEI-520/520A/620/820 supports up to 16 outputs. The MOSFET
specifications are shown in Table 37. The discrete outputs are suitable for
driving resistive loads, solenoids, relays, lamps, and other loads not
exceeding the specifications in Table 37. See the previous section, “CEI-
420/420A/520/520A/620/820 Discrete Inputs”, for additional information
regarding the CEI-820 discretes.

The CEI-220/420/420A/520/520A/620/820 use a MOSFET to drive the
output discrete to ground when turned on.
