DI specifications: Open terminal voltage 7 V or less, terminal current 1 mA.
Allowable ON residual voltage 1 V or less, allowable OFF-state
leakage current 0.1 mA or less
DO specifications: 4.5 to 28 V DC, max. 100 mA per output
Handling Precautions
• The DI/DO is general input/output. Use the DI/DO with the parameters set. By
default every DI/DO is set to DI.
• To use as DI:
• Gold contacts, etc., suitable for turning a microcurrent ON/OFF should
be used for the no-voltage make contacts. To handle the terminal current
during short-circuit and the open terminal voltage of this device, use
contacts with surplus minimum open/close capacity.
• When a semiconductor is used as a no-voltage make contact, use a
semiconductor whose voltage at both contact ends when the contact
is ON satisfies the allowable ON residual voltage. Additionally, use a
semiconductor whose OFF-state leakage current is within the allowable
limits.
