Control Output 1/2
Auxiliary Outputs 1/2
CT Input
• Terminals 7 and 8 are for control output 1 (OUT1) and terminals 1 and 2
are for control output 2 (OUT2).
Control output 1 Control output 2
Pulse voltage output type
E5ZN-2Q@H03@-FLK
• The following table shows the specifications for each output.
Output
12 VDC output voltage ± 15% (PNP)
Pulse voltage
Max. load current 21mA, with short-circuit protection circuit
Transistor Max. usage voltage 30 VDC, max. load current 100 mA.
Max. residual voltage 1.5 V, max. leakage current 0.4 mA
max.
• The pulse voltage output (control output) is not electrically insulated from
the internal circuits.
When using grounded thermocouples, do not connect any of the control
output terminals to the ground. If the terminals are connected to ground,
unwanted current paths may result in incorrect temperature measure-
ments.
• Terminals 13 and 15 are for auxiliary output 1 (SUB1) and terminals 14
and 15 are for auxiliary output 2 (SUB2.)
PNP (sourcing) type
E5ZN-2@PH03@-FLK
• The transistor output specifications are given below.
Maximum applicable voltage: 30 VDC, maximum load current: 50 mA.
Maximum residual voltage: 1.5 V, maximum leakage current: 0.4 mA.
• When the heater burnout alarm is used, connect a current transformer
(CT) across terminals 16 and 17 for channel 1 and terminals 16 and 18 for
channel 2 (no polarity).
• Use E54-CT1 or E54-CT3 Current Transformers.
