6ES7422-1HH00-0AA0 SIMATIC S7-400 Digital Output Module Relay 5A

6ES7422-1HH00-0AA0 SIMATIC S7-400 Relay Output Module

• Brand & Model: Siemens 6ES7422-1HH00-0AA0, part of the SIMATIC S7-400 series, SM 422 family.
• Output Channels: 16 digital outputs with relay contacts, galvanically isolated in groups of 2 channels.
• Load Voltage: AC rated 230 V (permissible 2–264 V), DC rated 60 V (permissible 1–60 V).
• Output Current: Rated 5 A per channel; minimum load current 11 mA for reliable switching.
• Switching Capacity: Resistive/inductive loads up to 5 A at 30 V DC or 230 V AC; lamp load max 60 W.
• Switching Frequency: Resistive 10 Hz, inductive 1 Hz, lamp 1 Hz, mechanical 20 Hz.
• Relay Durability: 100,000 electrical cycles (AC-15/DC-13) and 3,000,000 mechanical cycles.
• Power Loss: Typical 4.5 W; backplane bus current max 1 A at 5 V DC.
• Protection: No short-circuit protection; external fusing recommended for each output.
• Diagnostics: Green LED status indicator per channel; no built-in diagnostic function.
• Isolation: 1500 V AC tested; channels isolated from backplane bus and each other (group-wise).
• Cable Length: Shielded up to 1000 m, unshielded up to 600 m.
• Temperature & Current: Total group current 10 A up to 40 °C, 5 A up to 60 °C (10 A with fan at 60 °C).
• Dimensions: 25 mm width, 290 mm height, 210 mm depth; weight approx. 700 g.

Installation & Mounting Guidelines

• Install the 6ES7422-1HH00-0AA0 module in a standard S7-400 rack; ensure proper backplane connection.
• Do not parallel outputs for current uprating; this feature is not supported.
• For redundant load control, you may parallel two outputs with the same load voltage.
• Observe group current limits: 10 A up to 40 °C, 5 A up to 60 °C (or 10 A with fan at 60 °C).
• Use external fuses for short-circuit protection, as the module has no internal fuse.
• Maximum cable length: 1000 m shielded, 600 m unshielded for reliable signal integrity.

Frequently Asked Questions (FAQ)

• Q: Is the 6ES7422-1HH00-0AA0 a genuine Siemens module?
  A: Yes, we supply only 100% genuine, new original Siemens modules.
• Q: Can I use this relay module with 24 V DC loads?
  A: Yes, the DC permissible range is 1–60 V, so 24 V DC works perfectly.
• Q: What is the maximum switching frequency for inductive loads?
  A: For inductive loads, the max switching frequency is 1 Hz (according to IEC 60947-5-1 DC13/AC15).
• Q: Does this module have short-circuit protection?
  A: No, it does not have internal short-circuit protection. Please use external fuses for each output.
• Q: Can I parallel two outputs to get higher current?
  A: No, parallel switching for uprating is not allowed. Only redundant control is supported.
• Q: How many electrical cycles can the relay withstand?
  A: The relay lasts 100,000 electrical cycles (AC-15/DC-13) and 3,000,000 mechanical cycles.
• Q: What is the total current per group at 60 °C?
  A: At 60 °C, the max current is 5 A per group, or 10 A if you install a fan subassembly.
• Q: Can I return this module if it doesn't suit my application?
  A: Yes, we support a 30-day return policy for unused items in original packaging.
• Q: How long does delivery take?
  A: We ship within 5 days; transit time depends on your location (FedEx/UPS/DHL).
