Usable I/O Points (C200H-MD215)
To prevent overheating in the C200H-MD215 and prevent early failure of internal components, limit the number of
input points ON simultaneously. The number of points that can be on simultaneously depends on both the temper-
ature and the input voltage. (There is no limit to the number of output points that can be ON simultaneously.)

Note If the Unit is at room temperature it takes about 10 minutes for excessive heat to build up when all inputs are
turned ON, so all inputs can be turned ON simultaneously for testing.

Pin 6: Not used.
Pin 5: Dynamic data output logic setting
Pin 4: Input response time setting

Pin 1: Operation Mode Setting
Pin 1 is not used for the C200H-ID501 or C200H-ID215.
Pin 1 C200H-OD501/215 C200H-MD501/115/215
OFF 32-point static output mode 16-/16-point output static mode
ON 128-point dynamic output mode 128-point dynamic input mode
Pin 2: Pulse Input Setting
Use pin 2 only for the C200H-ID501, C200H-ID215, C200H-MD501, C200H-MD115, and C200H-MD215. The
C200H-MD501, C200H-MD115, and C200H-MD215 pin 2 settings are effective in static mode only (i.e., pin 1 is set
to OFF).
When this pin is set for pulse inputs, only inputs 08 to 15 of CN2 will be pulse inputs. The response time of any other
input regarded as a normal input is set according to the input response time setting with pin 4.
